The Boron Open Pit Mine is the largest open pit mine in California and supplies nearly half of the world's borates. Borates are used in the manufacture of glass, fiberglass, herbicides, ceramics, soaps and detergents, fluxes, fertilizers, and fire retardants. Mining operations (not necessarily as an open pit) have been going on at the site for over 130 years.
See the earthcache> on the formation of the deposit.
